1) Flu is not a serious threat to a healthy person. They conduct medical studies in which (young, healthy) people are deliberately infected with flu. That is considered acceptable medical practice because it poses basically zero risk of serious consequences to the test subjects.
However, flu viruses kill a lot of people every year. For example, in the US here is some data frome the CDC:

Vaccination would very probably cut transmission rates - so would, by the way, the proper use of good face masks. As a result, it would save lives. I'm not sure how many, but there would definitely be fewer fatalities. Whether that happens in healthy people or not is not my point. bilby's arguments do not seem to take into consideration the fatality rate, and seem applicable to other cases as well, like the flu.

2) We have already learned that getting infected doesn't produce immunity--you're immune to that version but it very well might not protect you from variants. The vaccine (other than the Chinese crap that's a killed-virus vaccine, provides about the same protection as prior infection--bad) provides better protection than prior infection.
No, we have not learned that. At least, I have not learned that, so I will ask you to provide good evidence of that. Here's a study supporting the opposite conclusion, comparing Pfizer's vaccine vs. prior infection.
Background Reports of waning vaccine-induced immunity against COVID-19 have begun to surface. With that, the comparable long-term protection conferred by previous infection with SARS-CoV-2 remains unclear. Methods We conducted a retrospective observational study comparing three groups...

The variant was 27 times more likely to break through Pfizer protection from January-February and cause symptoms than it was to penetrate natural immunity from the same period

Sure, you can find studies in the other direction. Jury seems to be still out on that one.
As for the "Chinese crap" , Sinopharm's vaccine is the most widely used vaccine over here, closely followed by AZ and then Sputnik. Combined they probably make up well over 90% of the vaccinations over here. And despite the government's serious negligence that resulted in many more fatalities than otherwise would have occurred, eventually things have improved a lot, the ICUs have plenty of room available, the number of daily covid fatalities has fallen sharply now is gradually falling still, with 234 fatalities in the past 14 days (out of a population of about 46 million). This is despite the fact that nearly all restrictions have been lifted - even mask wearing outdoors, though it's still mandatory indoors - and the fact that most people do not respect the remaining ones anyway. In short, the Chinese crap seems to work okay in the long run, even if it's less effective than AZ or Sputnik. But infection should work better than the dead virus vaccines, as it is with the current variant of the virus.
Incidentally, vaccination with Chinese crap is
accepted by European governments and by the US government, even though the US government does not seem to count prior infection at all and demands vaccination. That does not make sense to me: Why consider people vaccinated with dead-virus vaccines immunized, but reject the same for people who recovered from the virus? I can't make sense of that one.
